His agent, J.T. Johnson, denied any malicious actions from his client and said the highly-touted prospect has not failed a drug test. He went on to elaborate, saying that the retesting was due to ankle and knee injuries and not an illegal or banned substance.

In any case, the NFL’s red flag is one for any potential suitor. According to the report, several teams have Allen as the No. 1 wide receiver prospect heading into the NFL draft set to begin on April 25.

Allen is the leading all-time receiver at Cal, with 205 receptions in three seasons, which included three missed games in 2012.

He did not go through the NFL scouting combine due to the aforementioned ailments and could be further hurting his draft stock as a result of the latest development. Coupled with the latest news related to possible drug issues, it could cause teams to shy away from taking him early.
